e LOUISIANA OIL HEATER" This inventiony relates to oil treating 'methods and means, and has for an object j the provision of an apparatus eective to heat crude oil in order to facilitate its circulation through distributing pipes or pipe lines, the said invention also being intended to im* prove the condition of oil prior to its being delivered to a pipe line.

rlhe invention is adapted for use in association with a gunbarrel or a tank, and is intended to circulate the crude oil with hot water or treating compound through said tank and heater, the heated mixture being discharged from the heater into the top of the gun barrel or tank. rlhe' circulation is usually continued for a period of time which will result in separating the oil from the water and placing the oil in condition for a pipe line run. By reason of the presence of the invention in association with the parts mentioned, the equipment necessary to change the quality of the oil and reduce it to a condition where it can be run in a pipe line is of simple nature, as compared with boilers, pumps and other lines which are now commonly used in this art.

It is an object of this invention to produce a heater associated with circulating pipes leading to and from a tank or gun barrel, the same being effective to produce the results indicated through an efhcient and com'- paratively inexpensive process.

lVith the foregoing and other objects in View, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

ln describing the invention in detail, reference will be had to the accompanying drawings forming part of this application, wherein like characters denote corresponding parts in the several views, and in which- Figure l illustrates a sectional view of a heating apparatus embodying the invention;

Figure 2 illustrates a sectional view of the said device on the line .2-2 of Fig. l.

The heater proper, in the present embodiment of the invention, comprises an internal pipe 5 and a jacket 6 mounted in spaced re lation to each other to produce an annular Application led November 27, MSG. Serial No. 151,154.

chamber 7. The space between the pipe and jacket is closed at the ends by annular rings or heads 8 and 9, and the said pipe and acket are stayed and held in spaced relation toeach other between the heads by memberslO, such as rivets.k A smoke uptake cr stack 1l cornmunicates with the firing chamber which is contained within the pipe 5, and the jacket has a head or door l2 at one end which encloses the chamber 13 with which the stack communicates so that heat and products of combustion passing through the pipe 5 escape through the stack. This element 12 is pre# ided and made removable for the purpose of permitting access to the interior for making repairs to flanges or the like.

The jacket 6 has a manhole 14 with a suitable closure l5 of known construction, which should be effective to close the manhole with a leak-proof joint. y

The jacket G has n'pples or pipe connections 16, l? and 18, the latter of which is in- Lended as adrain for washing out the annular chamber and discharging sediment or the like, which may tend to foul the interior thereof. The nipple lois for the connection of a suction line or pipe i8 provided with a check VYalve i9, for the purpose of cond ming salt water or ltreating cempound and oil from the gun barrel or tank to the heater in order that it will cil-cplVl ter through l the annular el. The nipple 1T is connected to a d scharge line 2l) having a check valve 2l to conduct 'the het salt water or treating compound and oil from the heater to a lume on top of a gun barrel or stock tank. As such gun barrels or stock tanks are well known in the art, it is believed unnecessary for an understanding of one skilled in the art to illustrate a conventional type thereof.

rihe check valve on the suction line is to maintain het salt water or treating componnd within the circulating system and prevent it fre n returning to the bottom of the gun barrel, whereas the check valve on the discharge line is to prevent back pressure from the gas line, from forcing hot salt water or treating compound back into the heater. The check valve 24 on the gas line is to prevent the entrance of hot salt Water or treating compound into the gas line.

A gas line 22 is associated with the apparatus and a pipe 23 connects the gas line and the discharge line 20. The pipe 23 is coni nectedv to the discharge line ahead of the check valve 21 and the ressure in the gas line is emploed for furnishing pressure to push the lint Sa. t Water or treatno compound to the 1 flume on top of the gun barrel or tank. A check valve 24 is in the pipe 23 to prevent hot salt water or treating compound from gaining access to the gas line.

We claim:

f 1. An oil heater comprising a heat conductiugpi e and a jacket held in spaced relation to eac other with a channel therebetween, means for closing the ends of the channel, a communicating with the interior of the "eater near one end and adapted to communicate with a source of oil supply, a pipe communicating with the annular channel nearthe other end for returning oil to the said oil Supply, and pressure augmenting means com- 25 municating with the second mentioned pipe and adapted to be connected for delivering gas under pressure to force the oil back to the oil supply.

2. n oil heater comprising a heat conducting pipe and a jacket held in spaced re` lation Vto each other with a channel therebetween, means for closing the ends of the channel, a pipe communicating with the interior f the heater near one end and adapted to a5 communicate with a source `f oil supply, a

pipe communicating with the annular channel near the other end for returning oil to the said oil supply, a check valve in said pipe, a pipe communicating with the last mem tioned pipe in a location beyond the check valve, t e said pipe being adapted to deliverl under pressure t0 force the oil back to. the said oil supply.
